Lag spike causing disconnects

Over the past few weeks/month I have noticed that lag spikes cause me to momentarily disconnect from games (primarily World of Warcraft). I have followed all the troubleshooting for renewing IP and flushing DNS which blizzard suggests but with no improvements.

I have reset my router with a pinhole reset, but the problem still persists. It seems to be more common in the evening so I have started monitoring my connection and it shows the following; 

My Broadband Ping - VM Home Connection

 Each of the higher spikes causes me to disconnect from games. If I run a tracert to the suggest IP addresses on the blizzard support page I get the following return;

Re: Lag spike causing disconnects

Other than a restart at about 7pm there's nothing materially wrong showing in your BQM that I can see.  There's a peculiar and consistent sinusoidal variation in average latency with a cycle time of around 7 minutes that suggests a faulty piece of kit, either heat or capacitance cycling?  But I can't say that there's anything that explains the problem you describe.

Suggest you connect to the hub, and post the Downstream, Upstream and Network logs tabs in replies here, there might be evidence of problems in those.  Maybe run a series of speed tests to see if that shows anything.

Hopefully that is the information you were after. I have moved the hub to see if the environment is having any effect on it - will keep an eye on it but the monitor is continuing to show the same pattern or regular peaks.

Re: Lag spike causing disconnects

With my limited knowledge, there's nothing that looks significant in the logs - the odd T3 timeout or similar isn't a big deal, although it would be if they were daily.  Your downstream power levels are within spec, but only just (-5 dBmV is the accepted limit), and likewise the SNR is within spec but could be better.

But you might want to read this post in case there's any common factors.  Having said that, I wouldn't be at all surprised if your particular connection problems were sorted out by getting a Hub 3, because the load is spread across more channels, and the Puma chipset latency fix has been implemented. [Shouts out to the ether] "VM forum staff, can this customer have a new hub please?"

Should a Hub 3 materialise, be aware the default wifi settings are poor, and you may need to come back here to get advice on what works well.

Re: Lag spike causing disconnects

Thanks for the advice and help - I presume a call to VM customer support would help my cause in going about getting a Hub 3?

Probably not.  VM's first line telephone support is (intentionally) the worst in the world. [REMOVED]  But VM don't mind, because they don't care about customer service.  However, there is this link that might work for you?  But be careful:

1) The hub is always VM's property, you shouldn't pay a penny for them providing something that works, either as a setup or upgrade fee

2) Make sure that your existing contract price stays the same, and that VM don't try and declare you as starting a new contract.
